Thanks to all for helps, but codes give general rules, nothing like WRC107. I believe to define allowable loads I shall perform a finite element analysis. best regards

For steel vessel we refer to WRC107, but there is nothing for FRP tanks. I need to define allowable loads ( forces and moment ) acting on a nozzle. I will appreciate any suggestion and help. Manu thanks in advance.

Please, I need some information about this code. I shall appreciate every information, note or link about this code and where I may found it. Many thanks in advance

Thanks for the answer. This value for G is valid for ASCE 7-02 also ?

I wish to know how to calculate wind gust factor for piping. All data in ASCE are for buildings, but not for piping. Many thank for any informations.

Thanks CRG. I have checked, and what you say is right : in the table named "Template for drilling class .. " B16.5 1996 gives hole and bolt size. The problem is that the bolt size is in inch units only. For design guideline I use ASME VIII div.1, but my customer requires to use metric bolts...

Sorry, but my problem is to use a metric bolt ( M20, M30 and so on ) with B16.5 Flange. For example what metric bolt I must use for DN24'' 150#. B16.5 gives only Bolt hole diameter and not Bolt size. From manufacturers catalogs I have 1-1/4'' ( quite 31.75 mm ), but from bolt tables I have M30...

Problem : Use metric bolt on ANSI flanges. There are reference codes or rules to have the exact change ? Many thanks in advance.

I need to use metric bolt on Ansi 150# 24'' flanged joint. B16.5 requires 1-1/4'' bolt ( O.D. = 31.75 mm ) There is a code o standard rule to select M30 or M33 ? Or I must perform a calculation according to ASME code ? ( A bolt with OD=32 mm does not exist ) Many thanks in advance

Try PD5500:2300 appendix G

I need to check a reverse flange with stud-bolts. OD flange 813 mm Stud Bolts M39 OD 39 mm Bolt circumference diameter 749.3 mm Distance from the OD to bolt 12.35 mm I does not found any code ( ASME, BS, Eurocode ) that give me a rule to define the minimum distance between the bolt and the...

I refer to Par. J.3.8.3 of API650 The required safety factor of 4 is referred to Tensile strength or Yield Strength of material. Why I must double the load acting on a lug ? If a customer require 1.5 or 1.25 I may assume this value or I must assume 2 ? Many thanks in advance

I am intersted to buy english version of China codes. Someone could help me ? many thanks in advance.

Often, when I perform a stress analysis of pipe system ( B31.1 or B31.3 ) I have that at the flanged joints I have a lower than allowable stress. If I calculate the equivalent pressure Pe at the flanged joint location I have the ( Pd+Pe )> Prating. Due to the fact the ASME B31.1 and 3 do not...
